Product Information

As used on all our GTA-R builds. The brake balance box is CNC machined from billet aluminium.

To fit RHD only, this box directly replaces the standard brake master cylinder whether it is a single or dual circuit set up. It bolts onto the outside of the chassis leg using the standard fitment points, no modification is necessary. The kit is supplied with the optimum sized master cylinders depending on whether the car is fitted with Dunlop, ATE, 4-Pot or 6-Pot brakes.

It uses a pair of Girling race brake master cylinders with an adjustable balance bar allowing the front to rear brake bias to be very finely adjusted. A remote bias adjuster cable can be screwed onto the end of the bar to allow the bias to be adjusted from the cockpit whilst driving, great for track day and race use!

This kit uses a pair of race master cylinders, giving the ability to optimise the bore diameters, allowing the servos to be removed whilst still retaining optimum power. By not using the servos you get a dramatic improvement in the feel of the brakes allowing for far better modulation of brake pressure resulting in less chance of locking the wheels under heavy braking.

This pedal box is cheaper to fit than a reproduction RHD dual circuit master cylinder and a pair of servos! Those in the process of building fast road, track day or race cars from scratch have the unique opportunity to simultaneously improve the brake system.

A spherical joint is fitted in the front of the box where the pedal rod enters the box to ensure perfect free movement of the rod.
